Mathematics

$x = - 1\: or \: x = - 11$

Step-by-step explanation:

The given function is

f(x) = 2 |x + 6| - 4

We want to find the value of x, for which f(x) =6.

Let use equate the function to 6 and solve for x.

2 |x + 6| - 4 = 6

Add 4 to both sides to get:

$2 |x + 6| = 6 + 4 \\ 2 |x + 6| = 10$

Divide through by 2 to get:

|x + 6| = 5

Use the absolute value function definition to get:

$x + 6 = 5 \: or \: x + 6= - 5$

Subbtract 6 from both sides to get:

$x = 5 - 6\: or \: x = - 5 - 6$

$x = - 1 \: or \: x = - 11$
